SLIDING-PANEL HOLDER.

Application filed June 27,

This invention relates to a means for main taining a window, sliding panel or the like in selected position. Certain slidable members especially windows are arranged to be moved vertically in ways and are counterbalanced by weights so that at any position in their travel they will maintain that position unless acted upon by the operator. There are certain inherent disadvantages and faults which such windows are subject to, and the present invention appertains to means for maintaining such windows or like members in position and which require no wells or pockets for counterweights or the like.

The primary object of this invention is to provide a device permitting free one way movement of a slidable member decreasing friction as much as possible and yet yieldably holding it against movement in the other direction by causing friction to hold the panel where placed. In addition to the broader objects of this invention, there are certain details of design whereby a simple, economical, compact structure, easy to install and capable of withstanding hard usage is obtained. 7

These objects together with other objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawing, in which Fig. 1 is a sectional view through a fragment of a window frame and sash with my improved holder installed therein; Fig. 2 is a fragmentary elevation partly in section showing the devices applied to a double hung window; Fig. is an assembly of the rod and fastening plates; Fig. 4 is a plan view of the side of the window sash; Fig. 5 isa perspective view of a fragment of the upper corner of the window sash: and Fig. 6 is a.

transverse section through the holder.

Referring more particularly to the drawing, a window frame is indicated by 10. As no wells or weight pockets are needed for counter-weights this frame may be of substantially solid material and so arranged that flush casing and plaster returns can be economically used. The advantages of such construction will be obvious to those skilled in the building a rts. The usual stock window is used.

In the sash 11 at one side is a groove 12 for housing a rod. Countersunk in the upper 1927. Serial No. 201,731.

end of the sash is a plate 13. This plate is preferably of metal and covers the end of This plate has a bevelled head 18 adaptedto fit in the hole. in plate 17 and the other end thereof is threaded to receive the head 19. Head 19 is provided with a. kerf for a screw driver so that it may be adjusted up and down upon the rod 16 which is placed in position by passing it through the opening in plate 17, then slipping the adjustable head 19 into position and turning the latter so as to tighten the rod 16 and place it under tension between the plates. 1 l

A recess is formed in the. frame as indicated hyQO in Fig. 1. This recess serves to hold a casingQlhaving a selvage plate 22 j for attaching the casing in position. A seat 23 is formed for the rod 16 to rest therein.

In the plate 22 is an opening and extending therethrough is a catch lever 24 pivoted at one end as indicated by the pin 25. Extendin through the lever is an eye 26, and tending to hold. the lever in its lower position which is at an angle to the horizontal is a tension spring 2-7. The walls of the eye are such that when the lever is in its lower position as shown in Fig. 1, the axis of the eye will be inclined to the vertical.

Upon elevating the window, any drag upon the rod 16 caused by the lever will tend to lift the latter against the action of spring 27 so that the eye is positioned permitting the rod to freely move therethrough and trees the e 7 rod from seat 28. However, when the window is moved downwardly by gravity or otherwise, the eye lever is moved downwardly into the position shown in Fig. 1 tending to bite into the rod 16 and to pull the latter against the seat 23 in plate 22 thereby resist. ing the downward movement and ofi'ering sufiicient force to hold the window against its own weight. It will be obvious that the parts will be sodesigned that additional force exerted upon the window sash tending to move it downwardly will overcome the holding resistance. Thus, the window is held yieldably in position. The device yieldably resists n'iovement of the window in one direction and permits free movement in an opposite direction. Obviously the device is not limited in its application to windows or to any sliding member, and hereinafter the Words sliding panel is used to broadly cover any sliding member. Vi hereas the device is especially useful for sliding panels which are moved vertically, it will be appareat that it is not limited to such.

lVhat I claim is 1. The combination of a support, a panel slidablc thereon, a rod on said panel extend ing longitudinally of the path of travel of said panel, a tiltable arm secured to said support having an eye through which said rod is rove, said arm being normally maintained so that the walls of said eye will frictionally engage said rod and increasingly and yieldably grip the latter when said panel is moved in one direction and will be tilted to decreasingly grip said rod when said panel is moved in the opposite direction.

2. The combination of a frame, a panel slidably mounted in ways thereon, a rod on said panel extending longitudinally across the path of travel of said panel, a lever pivot ally secured to said frame having an eye through which said rod is rove, said lever being normally maintained so that the walls of said eye will frictionally engage said rod and increasingly and yieldably grip the latter when said panel is moved in one direction and will be tilted to decreasingly grip the rod When said panel is moved in the opposite direction.

3. The combination of a frame, a panel slidable in ways thereon, a rod on said panel extending longitudinally of the path of travel of said panel, a lever secured to said frame having an eye through which said rod is rove, resilient means tending to normally maintain said lever so that the walls of said eye will frictionally engage said rod and increasii'igly and yieldably grip the latter when said panel is moved in one direction and will be swung to decreasingly grip the rod when said panel moved in the opposite direction.

l The combination of a frame, a panel slidable in ways thereon, a rod on said panel extending longitudinally of the path of travel of said panel, a case n'iounted in said frame having a lever pivotally mounted therein and extending outwardly along the side of said panel, said lever having an eye through which said rod rove, a selvage plate having a seat for said rod, resilient means tending to normally maintain said lever so that the walls of said eye will frictionally and yieldably grip said rod and increase the grip as the latter moved thereihrough in one direction and will force said rod into said seat and will be swung to decreasingly grip and unseat the latter when moved in the opposite direction.

In witness that I claim the foregoing T have hereunto subscribed my name this 13th day of June, 1927.
